About the Opportunity

CornerStone Technology Talent Services is seeking a hands-on Cloud Administrator to support enterprise cloud infrastructure for a global organization expanding its U.S. IT team.

This position will provide local technical ownership and responsive support during U.S. business hours, working closely with infrastructure, network, security, and international IT teams. The broader environment supports approximately 20,000 employees and more than 18,000 endpoints and assets, with critical application workloads hosted in the cloud.

The ideal candidate can independently administer AWS infrastructure, troubleshoot production issues, manage access, and maintain secure, reliable cloud operations. Strong AWS experience and practical Azure administration experience are required. This is a hands-on individual contributor position focused on daily administration and operational improvement.

What You’ll Do

• Administer AWS infrastructure: Provision, configure, maintain, troubleshoot, restart, and secure EC2 instances supporting business applications.
• Support Azure operations: Administer and troubleshoot Azure resources, including virtual machines, access controls, storage, and related infrastructure services.
• Manage identity and access: Maintain cloud permissions, roles, policies, and administrative access using least-privilege principles and established security standards.
• Maintain cloud workloads: Monitor availability, performance, capacity, and resource health; investigate alerts and resolve infrastructure issues.
• Support cloud connectivity: Troubleshoot instance connectivity and infrastructure dependencies, partnering with network administrators on routing, security groups, firewall controls, and connectivity across AWS, Azure, and on-premises environments.
• Protect systems and data: Administer storage, backups, snapshots, and recovery procedures; support restoration testing and operational readiness.
• Improve operational security: Work with security engineers to address cloud configuration findings, strengthen access controls, and maintain appropriate logging and visibility.
• Automate routine administration: Use scripting and cloud management tools to improve consistency, reduce manual work, and streamline recurring tasks.
• Coordinate incident resolution: Investigate cloud infrastructure incidents, document findings, and coordinate handoffs with U.S. and international technical teams.
• Maintain documentation: Create and update operating procedures, configuration records, troubleshooting guides, and recovery instructions.
• Support controlled changes: Participate in infrastructure updates and maintenance activities, assessing dependencies and communicating potential business impact.

Required Qualifications

• At least three years of hands-on AWS administration experience, with approximately five years preferred.
• Practical Azure administration experience, generally one to three years.
• Demonstrated ability to independently provision, configure, troubleshoot, restart, and secure Amazon EC2 instances.
• Experience administering AWS identity and access controls, including IAM users, roles, and policies.
• Working knowledge of cloud networking concepts, including VPCs, subnets, routing, security groups, and network access controls.
• Experience supporting cloud virtual machines, storage, backups, monitoring, and operational troubleshooting.
• Ability to distinguish infrastructure, operating system, connectivity, and access issues and work with the appropriate teams to resolve them.
• Experience using scripts or automation tools to perform repeatable administrative tasks.
• Strong troubleshooting skills and sound judgment when supporting business-critical systems.
• Clear communication skills and the ability to work independently while coordinating with distributed technical teams.
• Ability to work onsite in Farmers Branch five days per week.

Preferred Qualifications

• Experience supporting cloud infrastructure in a large enterprise or global organization.
• Experience supporting environments spanning AWS, Azure, and on-premises infrastructure.
• Familiarity with cloud monitoring and logging tools, such as Amazon CloudWatch or Azure Monitor.
• Experience administering Windows Server, Linux, or both in cloud environments.
• Familiarity with infrastructure as code tools such as Terraform, AWS CloudFormation, or Azure deployment templates.
• Experience with backup recovery, disaster recovery exercises, change management, and incident documentation.
• Relevant AWS or Microsoft Azure certifications. Demonstrated hands-on capability carries more weight than certifications alone.

Why Consider This Opportunity?

• Take ownership of cloud administration as part of an expanding U.S. IT team.
• Support critical workloads within a substantial global enterprise environment.
• Apply both AWS and Azure skills while partnering with dedicated network and security professionals.
• Improve infrastructure reliability, administrative processes, documentation, and response times.
